Are carrots really good for your eyes?

Carrots are rich in vitamin A, which is essential for sight, but many other foods also contain this vitamin. A well-balanced diet, with or without carrots, provides all the vitamin A necessary for good vision.
Dr. Know debunks the myth that eating carrots will improve your vision. Learn more about vitamin A in this video from Discovery.

Because carrots are high in vitamin A and beta carotene, they are known to play a role in eye health. Vitamin A is an essential component of rhodopsin, a protein which absorbs light in the retinal receptors. Some studies indicate that Vitamin A may play a role in preventing degenerative eye disease brought on by aging.

"Eat your carrots, they're good for your eyes!" This oft-heard advice is rooted in truth: carrots and other colorful fruits and vegetables are rich in pigments known as carotenoids. Some carotenoids, such as beta carotene and alpha carotene, are known as provitamin A carotenoids, because they can be converted to vitamin A in the body. The most usable form of vitamin A, retinol, is essential to the proper function of the retina, the light-sensitive tissue lining the back of the eye.

Carrots, which contain vitamin A, are one of several vegetables that are good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, and lutein are even better. Antioxidant vitamins may help protect the eyes against cataract and age-related macular degeneration. But eating any vegetables or supplements containing these vitamins or substances will not prevent or correct basic vision problems such as nearsightedness or farsightedness.

When it comes to your eyes, Popeye trumps Bugs Bunny. While carrots are good for your eyes, they aren't as powerful as spinach. Research shows that your eyes enjoy more protective benefits from the lutein found in spinach than the beta-carotene found in carrots. That's what's up, doc.
